HOSEA H. HUNTLEY, OF QUINCY, ILLINOIS, ASSIGNOR TO MARY L. HUNT LEY, OF SAME PLACE.

lVlOLDERS FLASK.

SPECIFICATION forming part of Letters Patent No. 389,153, dated September 4, 1888.

Application liled January 20, 1888. Serial No. lfiLilflO.

To all whom it may concern.-

Be it known that I, HOSEA H. HUNTLEY, of Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Molders Flasks; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the accompanying drawings, forming a part of this specificatioinand to the [o figures and letters marked thereon.

The present invention relates to certain improvements in molders flasks, and has for its object to improve the hinge and guides for the two sections, the cope and drag, whereby the cope may be swung up on the hinge without liability of disarraugcment, may be separated from the drag in any positioinsave when opened to its greatest extent, and may be separated from the drag at either front or back without destroying the mold by sliding, as is frequently done when the ordinary hinge and guides are employed.

To these ends theinvention consists in certain novel features of construction and com binations and arrangements ofparts,to be here inafter described, and pointedoutparticularly in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a side elevation of a closed flask having my invention applied thereto. Fig. 2 is asimilar View with the sections opened. Fig. 3 is a perspective view of the hinge closed. Fig. 4 is a view from the other side with the two parts of the hinge separated. Fig. 5 is a View 5 of the two sections separated and opened out flat.

Similar letters of reference in the several figures indicate the same parts.

The hinge is composed of two sections, A

and 13, adapted to be secured, by screws or otherwise,to the inner faces ofthe two sections of the flask at the rear corners, so as to aid in strengthening and holding said corners together. The section A is secured to the cope 5 or upper part of the flask, and consists ofa hinge-plate having a hook, O, thereon, the inner surface of which forms a curved bearingsurface and its end a flat bearingsurlacefior a purpose to he presently described. Besides the hook O, the section A is provided with a (No model.)

pintle, D, and with a shoulder, (Z, the upper surface of which is flush with the surface of the hook 0, both being raised above the surface of the hinge-plate, so as to form shoulders E, against which the edge of the flask rests.

The lower section,B,ofthe hingeis provided with a hook, F, similar to hook C, only that it is recessed on the inside to accommodate the pintle D, and,instead of being provided with a pintle similar to D,it has only a short curved surface, G, and a square shoulder, H, against which the hook O rests when thehinge is thrown open, as shown clearly in Fig. 2.

On the forward-prejecting arm of one of the hinge-plates, at the edge, is formed a tapering lug, I, and on the other a corresponding recess, I, which registers therewith when the flask is closed, to aid in positioning and hold ing the parts firmly in place.

The front corners of the flask are provided on their inner surfaces with plates or angleirons K, for strengthening the joints, the plates on the cope being provided at their edges with downwardly projecting oblong lugs, or cars L and the plates on the drag with projections M, against which the forward edge ofprojection L rests when the two are brought together, thus effectually preventing any forward movement of the cope when the rear end is raised, as is necessarily done in making the molds for some castings.

In applying hinges such as above described the rear edges of the flask are brought against the shoulders E, the hinge-plate being set into the inner faces of the same, as will be readily Q understood from an inspection of Fig. 1. The sections of the hinges and the plates K hav ing been applied to the cope and drag, as heretofore described, it will be found that the two sections of the flask may be brought together and will register exactly without any special care on the part of the operator, and the cope may be swung open, pivoting on the pintles D of the hinges, until the flat ends of the hooks encounter the shoulders d and H and the in- 95 nor surface of hook O rests on the curved surface g, when it will be found that further motion will be arrested, and the cope, being back of its center of gravity, will stand of itself. (See Fig. 2.) Side motion of the copei s prc- 100 vented in one direction when open by the contact of the sides of the two hooks, and in the other direction by the engagement of the end of the pintle D with the endg of the curved surface g, and when closed by the above-named instrumentalities, as well as by the lugs I and L.

It will be noted that the hooks C and F do not surround the pintle or bearing-surface far enough to render the two parts non-detachable in every position except a closed one-a common fault with hinges heretofore constructed-- but extend only far enough to afford a firm bearing and permit the parts to be separated at any point during the outward movement of the cope by a direct upward lift on the rear end until a point is reached where the hook 0 passes under the bearingsurface g at nearly the extreme of the movement, the beveled corner of the projection aiding in this result by allowing the pintle to pass out in aslightlydiagonal direction. All liability of the cope slipping back off the drag is prevented, how ever, by the hook F, in which the pintle takes its bearing, as before described.

I am aware that it is not broadly new to construct a hinge for a molders flask with two pintles with Vshaped bearings thereon and two hooks engaging the same in such manner as to render the parts non-detachable save when in closed position, and I do not wish to be understood as claiming 'such construction.

Having thus described my invention,what I claim as new is- 1. In a molders flask,thecombinatiomwith thetwo sections, of a separable hinge secured thereto, having a pintle and hook on one section and a hook and limiting shoulder or stop on the other section, substantially as and for the purpose set forth.

gaging said hook on the other section, sub- 1 stantially as described, and for the purpose specified. 1

3. In a molders flask,the combination,with the two sections and a separable hinge secured thereto, having a pintle and hook on one section, of a bearing-surface and hook on the op posite section of such length as to engage the sides of the first-mentioned hook and pintle and prevent lateral displacement, as and for the purpose set forth.

4:. In a molders flask,the combination,with the two sections having sections of separable hinges secured thereto, of tapering guidepins formed integral with two of said sections at the sides of the flask, and corresponding opensided tapering recesses formed in the edges of the sections of hinge on the opposite section of the flask, whereby the parts are automatically positioned when closed.

5. In a molders flask,the combination, with the separable sections, of a flat guide pin or lug formed on the edge of one section, and a projection formed on the edge of the opposite section for engaging the forward edge of the pin or lug on said firstmentioned section for preventing the forward movement of one section upon the other when the rear end is raised, substantially as described.
